5.2 שלייף דעטעקציע פונקציע

The LSW3-GT-24NSR features a hardware switch for enabling or disabling the loop detection function. This function helps prevent network instability caused by accidental network loops.

Figure 4: Loop Detection Switch (ON/OFF).

• אויף: Loop detection is active. If a loop is detected, the corresponding port will be automatically shut down to prevent network broadcast storms, and the LOOP DETECT LED will illuminate.
• OFF: Loop detection is disabled.

It is recommended to keep the loop detection function ON for network stability.

• הומידיטי: 10% צו 85% (ניט-קאַנדענסינג)

7. טראָובלעשאָאָטינג

If you encounter issues with your BUFFALO Giga Switching Hub, refer to the following common problems and solutions.

7.1 קיין מאַכט

• סימפּטאָם: די POWER LED איז אַוועק.
• לייזונג: Check if the power cable is securely connected to both the device and the power outlet. Ensure the power outlet is functional.

7.2 No Link or Slow Speed on a Port

• סימפּטאָם: The LINK/ACT LED for a connected port is off, or the 1000/100/10M LED indicates a lower speed than expected (e.g., 100M instead of 1000M).
• לייזונג:
  • Verify the Ethernet cable is securely connected at both ends.
  • Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
  • פֿאַרבינדט דעם מיטל צו אַן אַנדער פּאָרט אויף דעם סוויטש.
  • Check the network adapter settings on the connected device (computer, server) to ensure it is configured for auto-negotiation or the correct speed.

7.3 Network Instability / LOOP DETECT LED is On

• סימפּטאָם: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
• לייזונג:
  • A network loop has been detected. This typically occurs when two ports on the same switch (or different switches) are connected to each other, creating an infinite data path.
  • Carefully inspect your network cabling to identify and remove any redundant connections that form a loop.
  • If the loop detection switch is ON, the affected port will be automatically shut down. Once the loop is resolved, the port should resume normal operation.
